My dad's birthday is in a few days and he's a big Star Trek fan. I thought about getting him the original series on DVD, but's from what I've seen the boxsets are really expensive and he already has the series on vhs (don't know if he'll touch the dvd's). I also thought about getting some sort of model ship or toy of some kind, but I don't know anything about Star Trek. I really want to get him something he wouldn't expect (so no ties, cards, watches, etc), but I don't know where to start. Anyone have any suggestions (preferably Star Trek related and under $200)?
